I have an older bike that has Campagnolo 8 speed record (carbon) and my rear shifter isn't holding gear. I tried to have it fixed at the LBS, but they didn't get the job done. I suspect a cracked housing. I am not sure what to do with this? I already spent money trying to fix this once and now thinking about sending it all the way out to Seattle to Branford Bikes to see if they can fix it. I am a little concerned in doing so because I asked them if they could make sure it holds gear prior to sending it back to me and their response was a roundabout no. I asked, can't you just test to see if it holds gear? They seemed to not understand. I am a handy person, but no certified Camagnolo mechanic and even I know how to test if it holds gear. That is VERY easy to do. I don't really want to buy a whole new drivetrain and fall into this silly 11 speed stuff that makes no sense to me. 8 is more than enough and this did last a very long time.
Anyone have any advice? I wish someone had an NOS shifter for sale somewhere, but I have had no luck in that either. Buying a used one may also be a dead end if it has the same issues.
